A copolymer 〈HSAs : EA/EMA/2-HEMA/AAEM) which is an acrylic resin containing 70% solid content was synthesized by the reaction of monomers, including ethyl acrylate, ethyl methacrylate, and 2-hydroxyethyl methacrylate with a functional monomer, such as acetoacetoxyethyl methacrylate, which may give improvements in cross-linking density and physical properties of films. The physical properties of prepared acrylic resins, HSA containing AAEM, are as follows : viscosity, 203~550cps ; Mn, 2590~2850 ; and conversion, 82~89%, respectively. It was found from the plotting of Tg versus viscosity and Tg versus molecular weight that viscosity increased with Tg while number averaged molecular weight decreased with increasing Tg.
